@he ehm-ge cirying eiemeiit C is plus' -vided with a plurality of chambers 45, hereinafter termed combustion chambers, the

`element C by meansof the gears 25 and 26,

an annular flange 50 being formed on one end of said charge carrying device, said flange being provided with interior teeth 51 arranged in meshing engagement with the gears 25 and 26. Thus it will be seen that when the shaft 18. is rotating the pinion 24 carried thereby will impart motion to the gears 25 and 26 in Aopposite directions, the latter in turn imparting motion to the charge carrying element C in a direction opposite to the direction of rotation of the 'rotor R. Of course, the gearing is `so timed 'that the combustion chambers pass the spark plugs or similar igniting devices at the proper time. Y

The explosive-directing plate P isprovided with a plurality of intake and exhaust vrecesses 54 and 55 communicating with the intake and exhaust conduits 56 and 57,', of which there are a plurality of pairs arranged on the end plates 13. Attention is directed to the fact that the intake and exhaust' conduits are arranged adjacent each other .invorder that the charge passing through the intake conduits may be pre-heated b the exhaust gases passing through the ex aust conduit. At predetermined intervals the explosive directin plate P is provided with In operation, an explosive charge is ap- .plied tothe intake conduit456 passing to a plurality o c arge directing portsv60 inclined and tapered in a direction of travel of the rotor ,R. In the engine described herewith. and shown in the drawings a set of four intake and exhaust conduits have been shown, this corresponding to a four cylinder engine of the ordinary reciproca ing type. However, when a plurality of units are e'mployed embodying the structure shown in Figs. 1 to 3 the combustion chambers and rotors of the respective unitsmay be relatively offset so that a continuous torque is produced. The charge carrying element is provided with a plurality. of chambers 62 which tendto lighten the same and permitv quick cooling of the engine after running.

A packing 63 is carried by the end. of the rotor R to prevent the escape of gases and the consequent waste of power.

the intake recess 54 formed in the charge directing plate P. A suitable pump is provided (not shown) for compressing the charge. As the chamber 45 passes over the intake 54 a portion of the charge -is delivered thereto. When the chamber 45 reaches the f Iaperture 60 theopenings 47 and 48 register and the spark plug is energized to ignite the charge. When thisoccurs the explosion acting through the aperture 60 upon the blade 35 of the rotor R causes rotation of the latter. This rotation is imparted in-an opposite direction, tol the charge carrying element C by means of thev gears 25. and 26 and pinion 24. The operation described in the foregoing takes place at four separate places in an engine embodying the structure as shown in the drawings, Abut of course, it is to be understoodthat any number of the explosive chambers maybe 'provided and may be arranged in any relation desired. I desire'to lay particular stress upon the novel arrangement of the oppositely rotating elements R and C as well as the stationary plate P, these elements entirely obviating the necessity of any spring operated valves, piston valves, or in fact any other type of valves, theplate P being essentially the only valve in the engine. The relative positions of the intake-and exhaust ports as well as the positions of the charge directing ports in the plate P render theuse of the engine vmore practicable than. the existing types ofV rotary combustion engines. When two units or more are used there can be no dead-center on the engine. By'dead-center, I mean of course, a point at which no explosion could occur without turning over the engine. This is not necessary when two or more units are used, the engine being practically self-start- ,ing. I d-o not lay any particular stress ,upon

the details of construction of my improved engine, since it will be readily seen that the principal features of the same reside in the -plate P and the Aop ositely rotated power producing elements and R. Any approved mechanism might' be employed for imparting motion tothe elements in opposite directions and therefore I do not desire to be limited to the `use of the gearsas shown.

Such details of construction may be changed when reducing the device to actual practice.

I desire to further direct attention to the fact that if desired the charge carrying dev ice and. rotor may rotate in thesame directipn by reversing the angles or' the charge directing ports. If necessary another set of exhaust ports may be provided to allow the pressure to become ,normal and to thoroughly remove dead gases. Also any number of combustion chambers maybe rovided, the provision of a greater number essening the necessary speed of the element Cf From the above description taken in connection with the accompanying drawing, it is thought that a clear and comprehensive understanding of the construction, opera- Ation and advantages of my invention may 4be had, and while I have-shown an scribed the device as embodying a specific structure, I desire that it be understood thatd dej such changes may be made in said structure as do not depart from the spirit and Scope of the invention as claimed.

Having thus fully described my invenl.

tion, what I claim as new and deslre to segcure yby Letters Patent, is:-

l. In a rotary internal combustion engine, the combinationof a casing, a charge directing stationary plate therein, a charge carrying element and a rotor arranged on said plate and revolving in opposite directions thereabout, and said plate being provided the combination'of a casing, a rotor therein,

a,..plate having charge directing ports and intake and exhaust ports, a charge carrying element formed with combustion chambers rotatable about said plate in a direction opposite to that of the rotor, said combustion chambers alternately registering with intake and charge directing ports to drive the. rotor.

4. In a rotary internal combustion engine, the combination of a casing, a charge carrying device rotatable in said casing, a stationary cylindrical charge directing plate concentrically arranged Within the casing, and a rotor concentrically arranged Within the casing and within said plate, said rotor and charge carrying element rotating in opposite directions on opposite sides of said chrge directing plate for the purpose speciie f5. In a rotary internal combustion engine the combination of a casing having en Walls, bearings in said end Walls, a shaft in said bearings, a rotor carried by said shaft and provided with a plurallty -of blades, a charge carrying element rotatable Within said casing and having a plurality of combustion chambers therem, a stationary cylindrical plate ymounted Within the charge carrying device, the latter rotatable thereabout, gearing for impartingv motion from said rotor shaft to said charge carrying clement, said rotor and charge carrying element rotating in opposite directions, said charge directing plate having a plurality of ports therein for affording communication' between the combustion chambers, atA times, and said rotor, means for igniting the charge Within said combustion chamber when the latter is in communication With the rotor, and intake and exhaust conduits associated With said charge directing plate.

In testimony whereof, I aix my s1gnature hereto.

MARSHALL K THAYER.
